The First 40 hours of work per week are for survival. Everything after that is for success.
If there is a better solution... find it.
I have not failed 10,000 times. I have succeeded in proving that those 10,000 ways will not work.

Nature is truly wonderful. Only man is truly foul.
My success is due more to my ability to work continuously on one thing without stopping than to any other single quality.
